  • The purpose of this study is to analyze the relationship between early childhood teachers' play teaching efficacy and play sensitivity and children's play immersion, and to investigate the effect of play teaching efficacy and play sensitivity on children's play immersion. To this end, a survey was conducted targeting 359 early childhood teachers working in kindergartens and daycare centers located in J province. The research tools used in this study were 'Efficacy in Play Teaching' and 'Teacher's Play Sensitivity Scale' targeting teachers and 'Infant Play Immersion Test' targeting infants. As a result of the study, first, the correlation between play teaching efficacy and play sensitivity and young children's play immersion showed that there was a positive correlation between all variables other than the transformation of the sense of time among the teacher's play sensitivity sub-factors and play observation and children's play immersion sub-factors. Second, as a result of examining the effect of teacher's play teaching efficacy and play sensitivity on young children's play immersion, it was found to have a partially statistically significant effect.

  • There is substantial evidence that insulin sensitivity can be enhanced through appropriate dietary management . In this study, insulin sensitivity was evaluated using and insulin suppression test. Male Sprague-Dawley rats, were caused to be in a diabetic condition by the injection of streptozotocin, and divided into four groups. They were fed one of the following diets for 2 weeks : (group 1) a high-carbohydrate(CHO) low-fat low-fiber diet, (group 2) a high CHO low-fat and high-fiber diet, (group 3) a low-CHO high-fat and low-fiber diet, and (group 4) a low-CHO low-fat diet groups (as comparison between group 1 and group 2 shows). In the low-CHO high-fat diet groups, dietary fiber tended to decrease plasma glucose levels at the end of the experiment, but not significantly (as comparison between group 3 and group 4 shows). The average steady state plasma glucose level in rats on the group 3 diet was the highest among all four groups(p<0.05), indicating the poorest insulin sensitivity . However, high fiber increased insulin sensitivity in rats on the low-CHO high-fat diets(as shows by a comparison between group 3 and group 4). On the other hand , the high-CHO low-fat enhanced insulin sensitivity in rats on the low fiber diet(group 1 and group 3). The degree of enhancement of insulin sensitivity depends on the combination of CHO, fat , and fiber in the diet. In conclusion, this study demonstrates that a low-CHO high-fat low -fiber diet may be deleterious to diabetic rats. In view of insulin sensitivity enhancement , dietary fiber level is irrelevant, as long as the diet has a high-CHO and low-fat level.

  • The current study was undertaken to determine the effects of the ratios of dietary fat to carbohydrate and energy restriction on insulin sensitivity in the growing rats. Male rats weighting 80-90g were fed experimental diets for two weeks. Rats were killed and epiddymal adipose tissue were removed and sliced. Explants of adipose tissues were incubated for 2 hours in KRB(Krebs-Ringer bicarbonate) buffer containing various concentrations of human insulin and [U-14C]glucose. Insulin sensitivity was determined as glucose conversion to total lipids (lipogenesis) during 2 hr incubation. Exp't I : Effects of Ratios of Fat to Carbohydrate on Insulin Sensitivity. Eighteen male rats were fed 3 diets for 2 weeks. Diet 1 was low fat-high carbohydrate (4% soybean oil and 66.5% cornstarch) ; diet 2, medium fat-medium sarbohydrate(12% soybean oil and 58.5% cornstarch) ; diet 3, high fat-low carbohydrate (20% soybean oil and 50.5% cornstarch). Insulin sensitivity was higher in the order of LF-HC, MF-HC and HF-LC diet groups (p<0.05), i.e, lipogenesis was higher at all insuline concentration in the explants from rats fed LF-HC diet. However, thers was no significant difference in body weight gain and epididymal adipose tissue weight among treatments. Exp't II ; Effects of Energy Restriction on Insulin Sensitivity. Twelve rats were grouped into ad libitum feeding and restricted feeding(70% of ad libitum). The experimental diet was medium fat-medium carbohydrat diet as used in the Exp't I. Restricted feeding group tended to show higher insulin sensitivity compared to ad libitum group. However, there was no statistical difference between two groups. As expected, body weight gain and epididymal adipose tissue were higher in the ad libitum group. In summary, the resutls of the current study showed that the epididymal adipose tissue taken from the rats fed low fat-high carbohydrate diet showed higher insulin sensitivity compared to those fed high fat-low carbohydrate, and that resticted feeding tended to elevate insulin sensitivity in these tissues.

  • Sensitivity analysis is used to determine the effect of a change in a design parameter on the total system, and the calculated sensitivity is an important indicator of the improvement of a structure. In this study, we investigated the method of deriving and analyzing the sensitivity of design parameters by using finite element analysis and the method of improving a structure by using sensitivity analysis results. Design parameters for weight reduction design were selected using actual semiconductor inspection equipment that requires structural improvement, and the sensitivity to design parameters was calculated by using and finite difference method. We propose an improvement method that can reduce the weight while maintaining the transient response required by the equipment. By using the results of the sensitivity analysis through finite element analysis and finite difference method, we can create a structurally improved design that satisfies the desired stress or displacement by improving the design of the structure. Therefore, sensitivity analysis is applicable to various fields as well as semiconductor inspection equipment.

  • Objectives: The purpose of this study was to investigate the relationship between periodontal disease, number of remaining teeth with high-sensitivity C-Reactive protein in Korean adults aged 40 and older. Methods: The study used the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI-3), 2015. The study sample consisted of 3,883 aged 40 years or older who had completed the health survey and the health examination. Logistic regression analyses were performed to examine the odds ratios of high-sensitivity C-Reactive protein by periodontal disease and number of remaining teeth, adjusting for demographic characteristics, chronic diseases and oral health behavior-related variables. Results: When the demographic and chronic diseases were adjusted, the risk of high-sensitivity C-Reactive protein (hs-CRP) average 1.23 mg/L or higher was 1.36 times higher in patients with periodontal disease between the ages of 40 and 49, but it was not significant (OR=1.36; 95% CI=0.82-2.23). In addition, in the group of 0~23 remaining teeth aged 40~49 years, the risk of higher than the average 1.23 mg/L of high-sensitivity C-Reactive protein was 2.03 times higher (OR=2.03; 95% CI=1.10-3.74), and 1.49 times higher in 60~69 years (OR=1.07; 95% CI=1.04-2.76). Conclusions: This study found that periodontal disease and tooth loss in Korean adults aged 40 and older was significantly associated with high-sensitivity C-reactive protein.
